Zeller could be the surprise of the season. He started to play well at the end of last year once he got healthy. He's also been behind Side Show for the two seasons, and hey, he was playing for Cleveland, I wouldn't put them in the top of the list of teams that have a good locker room and develops young talent well.
Zeller in college would beat just about everyone down the floor, even if he got the board, which is some thing I think Stevens and DA have been looking for. Remember how Perk use to run the floor, and get easy buckets from Rondo in the breaks? I could see Zeller doing that. He also has a nice 15 footer that will help spread things out.
He's not going to be a shot blocker, but he can get to the spots quick and change shots. Which could be more beneficial than having a guy that can get 2 or 3 blocks a game, but gives up 10 buckets because he can't rotate quick enough.
